But it's VERY disappointing that almost no information at all is included about the recordings. Especially, no recording dates, not even the fact that some of these recordings are on various forms of piano roll, such as the Mahler and Debussy.

And some tracks, such as CD 2 track 03. Des Knaben Wunderhorn, don't really tell what's being played. In this example, the Wunderhorn songs are a collection - which song is being played?

On others, such as the Bartok Rumanian Dances, he recorded more than once -- which one is in this set?

Do you have complete information about these recordings, and a proper complete tracklist? These would be very much appreciated!
